(4302) Markeev Main-belt Asteroid
Discovered on 22 April 1968 by T. M. Smirnova at Nauchnyj.
Named in honor of Anatolij Pavlovich Markeev, professor at the Moscow Aviation Institute, well-known expert on theoretical and celestial mechanics. He investigated the stability of Hamiltonian systems in the case of resonances of the third and the fourth orders, constructed theories of motion in the vicinity of the libration points of the three-body problem and developed a theory of the motion of large constructions at the near-Earth orbits. In addition, he studied various cases of motion of rigid bodies on smooth and rough surfaces. He contributed much to the methods of teaching and published a number of textbooks and monographs.
